Based on the Belgian FN FNC. Very energetic, but a bit dumb.----* BerserkButton: Sensei repeatedly talking about her thong.* CombatPragmatist: She will often do things that seem unconventional, such as shooting through a fountain, or skipping bullets off water to hit someone not directly in her LOS.* EmbarrassingNickname: Doesn't like her nickname because she thinks it sounds weird.* EvenTheGirlsWantHer[=/=]ChickMagnet: Sako, Sig and Aug are [[IncrediblyLamePun all gunning]] for her.* GenkiGirl* HotForTeacher: Has a long-running crush on Sensei/Genkoku.* [[MrExposition Ms. Exposition]]: She is usually the one who tells Japanese Teacher, and by extension the audience, how the universe works.* RedEyesTakeWarning: Has red eyes. In a bit of a subversion, is generally a nice girl.* YouGottaHaveBlueHair: Light Purple

Funco's best friend. Kind, but has a rough personality and a foul mouth. Based on the American [=M16A4=].----* BathingBeauty: She likes to keep herself clean. This references the tendency of the M16 getting dirty and need of maintenance to properly function.* BerserkButton: Lame puns, specifically Ichiyon's.* CombatPragmatist: Keeps her barrel wrapped in a plastic bag when she needs to run through mud, and when her action gets mucked up, she works the forward assist by fanning it (cribbing a technique used for rapid-firing a single-action revolver).* GenreSavvy: She does as well as she does because she is very aware of her own shortcomings, and works to overcome or mitigate them.* HairDecorations: Her orange-shaped hair clip.* HappilyAdopted: She was adopted into Ichiyon/14's family (Ichiyon was produced by Springfield, while Ichiroku was produced by Armalite and Colt). Funco states that the clearest way to describe it in human terms is to say they're stepsisters.* TheIdiotFromOsaka: While not explicitly stated to be from the Kansai region, she speaks in an Osakan accent and has many of the mannerisms: silly, cheerful, stubborn, foul-mouthed.* TheIllegible: Her writing is bad enough that when she writes "Funco" (フンコ) in her diary she reads it as "Fucco" (フッコ). ** Funco, not knowing about the diary, mistakes this for Ichiroku doing her a favor by not using [[EmbarrassingNickname the nickname that she hates]]. Ichiroku lets her keep believing that.* JerkWithAHeartOfGold: She's somewhat foul-mouthed and unpleasant but she also cares.* PhenotypeStereotype: Combined with a KansaiRegionalAccent and its [[TheIdiotFromOsaka associated character archetype]], she's pretty much designed to be how Japan interprets Americans as.* {{Shorttank}}

A shy and clumsy girl who is also close to Funco. She idolizes Faru, Funco's older sister. She's based on the British [=L85A1=].----* BringMyBrownPants: Suffers one in chapter 6 of the manga after her skirt is clipped by a stray bullet.* ButtMonkey: Heavy emphasis there on "Wash and Scrub!".* CuteClumsyGirl* GagBoobs: Has the largest bust size among the middle school girls, a reference to how the [=L85A1=] is unusually heavy for an assault rifle.* IllGirl: Gets sick (breaks down) often, on account of the [=L85A1=]'s infamously poor reliability.* InnerMonologue* ParasolOfPrettiness: Is shown a lot with her beloved umbrella.* PerpetualPoverty* TheQuietOne* ShrinkingViolet: Very quiet, hardly says anything at all.

Another of Funco's friends. Gifted in both academics and athletics, she is very competitive and hates to lose. She's implied to have a crush on Funco. She's based on the Swiss SG 550.----* BecauseYouWereNiceToMe: She's clingy to FNC because she's the first person to ''ever'' be friendly to her at the school.* BigDamnHeroes: Often* ClingyJealousGirl: While not too clingy, she shows some signs of the jealous part for Funco when Ichiroku finishes "cleaning" her in Episode 3 [[spoiler:and when she watches Sako kissing her in Episode 6.]]** Comes out full force when FNC starts to befriend Mimi.* CombatPragmatist: Doesn't mind using G3's special position.* FriendlySniper: Nice to her friends, and finds amusement and enjoyment in her sniper duel with [=G3=].* GeniusDitz: A smart student, capable athlete, refined ojou, excellent sniper... and clueless about a lot of things in the real world.* {{Odango}}:** SlipknotPonytail[=/=]CloseCallHaircut: She loses it temporarily [[spoiler:after the jungle wargame arc when Sako tries to shoot her from the bushes.]] It grows back by the time the friends head to Enoshima.* SingleTargetSexuality: For Funco.

16's cousin and Funco's roommate. Based on the [=AR-18=].----* ButNotTooForeign: She is part American and part Japanese. This references the fact that she was designed by [=ArmaLite=] and one of her manufacturers is HOWA Machinery Co.* [[OnlySaneMan Only Sane Assault Rifle]]: Compared to her four friends, Ichihachi is less goofy and a LOT more down-to-earth. She also seems to spot details that Funco or Ichiroku might brush off -- like G3 coming to school in her sister's place.

A transfer student from another school alongside Galil, Sako plots to take over Seisho Academy Middle School by humiliating the best students. To do this, she plans on winning the jungle wargames tournament sponsored by the school. Based on the Finnish [=SAKO RK95 TP=], export version.----* AxCrazy* [[spoiler:BigDamnHeroes: Saves Ichiroku and Sig from the pincer attack in episode 10. She doesn't do this in the manga.]]* BloodKnight* CloseCallHaircut: [[spoiler:Sig]] returns the favor by shooting off Sako's side braid.* ColdSniper* CombatSadomasochist: In the animated jungle wargames tournament (which originally takes place in the manga mind you), she actually feels herself up during the fight against Funco's team. She pretty much gets off on shooting Funco after she's already won the match.** SexIsViolence: Gets turned on after watching Funco shoot Galil.* FlowerInHerHair* {{Jerkass}}* KickThemWhileTheyAreDown: After pinning down Funco, Sako repeatedly shoots her even after she won.* KnightOfCerebus: Her blood chillingly sadistic torture of Funco and attempted murder of Sig via sniper rifle coldly reminds the audience that ''Upotte'' is about weapons fighting battles, and in battles people die...* PointyEars* PsychoLesbian* PutOnABus: In the manga, however...** TheBusCameBack: ... she's back for the end of the Atami shootout in the anime, taking over Galil's role.* RedEyesTakeWarning* TriggerHappy* TryingToCatchMeFightingDirty: She uses any opportunity to cheat during the jungle wargame arc.* VillainousCrush: Falls for Funco** InLoveWithYourCarnage: Watching Funco take down Galil really turned her on.

Sako's partner and a fellow transferee. Like her, Galil plans on defeating the best students of Seisho Academy in the jungle wargames tournament. She stays in Seishou after the wargames end. Is a little slow. Based on the Israeli Galil AR.----* BecauseYouWereNiceToMe: Part of the reason why she sticks to Ichihachi ever since. Well, that, and Ichihachi ''did'' fish her out of the lake.* CuteLittleFangs* GirlishPigtails* LittleBitBeastly: Has the animal-ears and tail, like the AK series characters.** [[CatGirl Dog Girl]]:... but is actually a dog.* OddFriendship: Befriends 18 after she pulls her out the water, and sticks to her ''like glue'' ever since.* ZettaiRyouiki: Grade A

Friend and partner of Aug. Like her friend, she is a member of the middle-school student council, and serves as the Treasurer. Based on the Taiwanese[[note]]Republic of China's[[/note]] T91.---- * GirlishPigtails: Six of them and Ichiroku calls her "fountain" because of it.* [[ChineseGirl Taiwanese Girl]]* VerbalTic: Ends her sentences with "~ne."* ZettaiRyouiki: In the manga.

One of FNC's classmates, and secretly one of her biggest fangirls. She serves on the Middle School student council as its President. Based on the Austrian Steyr [=AUG A1=].----* CompressedHair* HairTriggerTemper: Pun not intended, but while in her long-haired mode Aug gets angry ''very'' easily, to the point where she picks a fight with Miss Thompson over a relatively trivial matter.* {{Meganekko}}* MultiformBalance: Can switch between a short barrel or a long barrel.* SplitPersonalityMakeover: She could be short haired shy girl or long haired boisterous girl. This references the fact that she can change barrels depending on the situation.* StudentCouncilPresident: As revealed in Upotte Nano.

One of G3's two little sisters who are in the middle school-level, and the one who looks like her the most. Based on the [=HK33E=].----* AlphaBitch: She's incredibly snooty and likes to brag about her reliability as a gun.* ApologisesALot: Only when she's getting scolded by the teachers. Also comes with excessive bowing, sometimes going all the way down to her feet.* BeautyMark: Has one below her left eye.* BerserkButton: Absolutely hates nicknames given to her such as "Chuusuri" or "Mimi".* InSeriesNickname: Mid-33/Chuusuri and Mimi.* {{Keigo}}* StrongFamilyResemblance: To [=G3=]. To the point where they can (mostly) stand in for each other. She's half a head shorter, and has a different "magazine" size than her sister though.* TomboyishPonytail: To differentiate her from the rest of her sisters.* {{Tsundere}}: Unintentionally labeled as this, due to switching out with her elder sister G3 for a day.

----!!Fem/[=Ak5=]

Based on the [=FNC=]'s Swedish cousin, the Bofors [=Ak5=] assault rifle.----

[[/folder]]

[[folder:High School (Battle Rifles)]]Guns who fire larger rounds like the [=7.62x51mm=] rounds.

Funco's older sister. A popular and beautiful girl who gets very good grades and is considered a natural class leader. She's based on the British [=L1A1=] SLR, a semi-auto-only FN FAL. ----* AwesomenessByAnalysis: During the battle against the Italian guns [[note]][=AR70/90=], SPAS-12, Benelli M4, BM59[[/note]], FAL notices that [[spoiler: the [=AR70/90=] in the battle is a decoy (actually [=AR70=]) just by looking at the change of material on her watch.]] * CoolBigSis* OneeSama* StudentCouncilPresident: For the High School-level.

Ichiroku's older sister, and FAL's roommate at the high school dormitory. Beautiful, but crude and rowdy. Also likes making bad puns. She's based on the American M14.----* BerserkButton: Ichiroku insulting her puns.* TheDitz* TheDreaded[=/=]OhCrap: Her nickname is a comedic version of the former and invokes the latter: The G stands for [[spoiler: God not again]]* HotBlooded: Quite so.* ImperialStormtrooperMarksmanshipAcademy: When firing her M14 on full auto. Possibly in reference to the early, full-auto capable versions of the M14, which were impossible to control in that mode - according to 16, her spread is about 10 ''meters''. The uselessness of this feature resulted in the full auto trigger group being locked on semi-auto or removed entirely from almost all M14-style rifles made since.* InSeriesNickname: G Cutie. (The "G" stands for [[spoiler:"God, not again."]])* IncrediblyLamePun: Much to everyone's annoyance, Ichiyon ''loves'' dishing these out.

A skilled sniper, but also very kind. Based on the German [=G3A3=].----* BloodKnight: Gets ''way'' too excited during fights.* CombatPragmatist: Willing to use a recoil-reducing shooting position that causes her to [[PantyShot flash her underwear at her opponent]].* FriendlySniper* HimeCut* OneeSama: To the rest of the HK sisters in the middle and elementary schools.* ProperTightsWithASkirt: A representation of the rifle's all-black fixed polymer stock.* StrongFamilyResemblance: All of her sisters strongly resemble her; in reality, nearly all of Heckler & Koch's product lines in the Cold War were derived from the G3.

!!AR-10One of G3, M14, and FAL's classmates. Obviously based on the American AR-10, which means that she's related to Ichihachi, at least on her non-Japanese side. Featured in ''Upotte Nano''.----

!!LF-59AR-10's friend, and yet another of G3, M14, and FAL's classmates. Based on the Italian Franchi LF-59, which is derived from the FN-FAL. She takes over for G3 during the Enoshima trip when the former is forced to attend remedial classes. Featured in ''Upotte Nano'', as well as the main manga.----* SempaiKouhai: Sempai to both AR 70/90 and SPAS-12.

[[/folder]]

[[folder:Elementary School (Submachine Guns)]]Guns who fire pistol rounds like the [=9x19mm=] rounds. (There are some exceptions)

One of G3's little sisters. Based on the [=MP5A2=]. Can be seen as the viewpoint character for the elementary school portions of ''Upotte Nano''.----* AccidentalMisnaming: Funco and the other middle schoolers call her "wee-3"[[note]]"chii-3" in the original Japanese (a mix of chiisai and 3)[[/note]] due to looking like her older sister G3.* CavalierCompetitor: Doesn't really care for the position of "leader" that Uzi think she holds, and is perfectly willing to give it up, but Uzi keeps on pushing the issue.* IdiotHair* StrongFamilyResemblance: Looks like a loli [=G3=] - because the [=MP5=] is essentially a [=G3=] in submachinegun size, chambered for 9mm. Taken further in that her "younger" sisters, [=MP5K=] and [=MP5SD=], could pass for being triplets with her.

Based on the American MAC-10.----* GirlishPigtails* HiddenBuxom: She's apparently quite stacked. Reflects how the real-life M10 is top-heavy and tiring to handle for long.* MotorMouth: A reference to her ridiculously high firing rate of ''[[MoreDakka 1090 rounds per minute.]]''* TheQuietOne: ...However she turns into this when she runs out of bullets.* YouthfulFreckles

!!Reta

One of Empi's friends. Based on the Italian Beretta M125.----* NiceHat* YouthfulFreckles

!!Cobra

Yet another of Empi's classmates. Based on the Finnish Jatimatic.----* BeautifulAllAlong: Much to the shock of everyone.* CoolShades: Is almost never seen without her sunglasses. Apparently she only takes them off when she's bathing.* GirlishPigtails* GoingCommando: Implied by TMP.* OnlyKnownByTheirNickname: ''No one'' ever calls her by her real name, and instead they just name her after the [[Film/{{Cobra}} movie]] that made the gun famous.

!!Uzi

One of Empi's classmates, who wants to be the "leader" of the elementary schoolers. As she thinks that Empi is the leader, she keeps on challenging her in order to take her place. Obviously based on the first model in the Israeli line of Uzi submachineguns.----* CanineCompanion: After Chapter 4 in ''Upotte Nano'', she got herself a wolf companion that she can ride. * TheRival: To Empi, or at least she thinks she is.

Another of G3's younger sisters. Despite being an elementary-schooler, she has the same height and figure as a middle-schooler. Based on the German [=HK53=].----* HugeSchoolgirl: She is as tall as a middle school student; it is something that embarrasses her. It is a reference to her firing assault rifle rounds instead of pistol rounds like other [=SMGs=].* StrongFamilyResemblance: To [=G3=], [=MP5=] and [=HK33E=]. However, she wears the standard Atami uniform and not the uniform worn by her sisters because the particular variant of the [=HK53=] that she's based on, the A3 variant, uses a retractable stock, unlike the solid fixed stock on the other G3 derivatives.

!!Tampi/TMP

Aug's younger sister, and the "boss" of the grade school dorm (much to Uzi's chagrin). Blunt and more than a little too sure about herself and her sister.----* TheAce* BrutalHonesty* GoingCommando: Apparently lacking a stock causes this.* {{Pride}}

A human middle school teacher who teaches modern literature. Despite specializing in Japanese literature, he's apparently not Japanese himself ([[spoiler: He's American]]).----* DrivingQuestion: What is his name and nationality?* EpicFail: At the {{Jerkass}}' shooting gallery, all his shots hit Funco instead.* EveryoneCallsHimBarkeep: Is mostly called "Sensei" or "Modern Lit."** Conversed and Lampshaded in episode 7, when Funco asks what his name is. 16, L and Sig all reply with "Japanese teacher."* TheFaceless: for most of the first episode.* InnocentlyInsensitive* MeaningfulName: His surname is [[spoiler: Browning]].* OnlySaneMan: Except when it comes to women.* TokenHuman: Of the faculty.* TooDumbToLive: His constant reference to Funco's thong.

A strict-looking high school teacher. Based on the German[[note]]Nazi Germany in fact[[/note]] [=FG42=].----* BeautifulAllAlong: When she drops the uniformed look for the seaside school. So much so that "Sensei" is taken aback.[[note]]Neither did he recognize her.[[/note]]* CloudCuckooLander: Ate flowers when experimenting with growing edible plants.* TheComicallySerious* EyePatchOfPower* MsFanservice: In the OVA she appears topless.

A teacher. He supervises daily target practice, and is dressed as a World War 2 [[SemperFi USMC]] [[DrillSergeantNasty Drill Instructor]]. Based on the American [[http://en.wikipedia.org/wiki/M1_Garand M1 Garand]] rifle.----* DrillSergeantNasty: USMC DI. It's in the job description.* SpellMyNameWithAnS: His name is commonly spelled "Garland", but the actual rifle is spelled "Garand".* SternTeacher: Very. He's quite pissed off when Funco, Ichiroku and Eru skip long range target shooting and try to pass off Shigu's shots as their own.

An elementary school teacher. Based on the American [[http://en.wikipedia.org/wiki/Thompson_submachine_gun Thompson sub-machine gun]].----* TheDitz* GagBoobs: {{Lampshaded}} by one of the [=HK=] sisters in Nano.* MamaBear: When Aug started shooting her students, she brings her old gangster self back to protect the kids.* MsFanservice: In episode 8 she was all dressed up in a really long webbed strap, which just barely covered her body.* PhenotypeStereotype: Three for three of the American guns rendered as girls.* TheRoaringTwenties: Originated from that decade where she was used by both law enforcement and gangsters; was later used by the military in World War 2.* SurprisinglyGoodEnglish: Says a few phrases in English which are well pronounced with an American accent. It does help that her seiyu, Creator/SayakaOhara, can speak good English.

The personification of the Japanese Howa Type 64 Battle Rifle. As she is chambered for 7.62x51mm NATO rounds, this means she is on the same year level as G3, FAL, and M14. Assumed to be one of Ichihachi's cousins on her Japanese side. Featured in ''Upotte Nano.''----* CoolBigSis* HairDecorations: A flower hairpin.* HimeCut* FriendlySniper: Despite being a battle rifle, she seems to fill this role.* OneeSama* YamatoNadeshiko: Even wears a traditional kimono to complete the look.

An assault rifle who met up with the friends on their trip to Enoshima. While being a gun personification like Funco and her friends, the school that she goes to is a normal public school, meaning that it's attended by human students. She seems to have a history with Funco, which makes things awkward when around her. She obviously is based on the Italian Beretta AR70/90 [[http://en.wikipedia.org/wiki/Beretta_AR70/90]].----* HoneyTrap: Tries this to get the teacher to stay in Enoshima. It doesn't really work.* ImpersonationGambit: She does one of these to perform the above, and has her older sister [=AR70=] stand-in as her. [=HK33=] manages to figure out the deception.[[note]]Both the [=AR70=] and [=AR70/90=] have the same chambering, but have different rifling rates optimized for different 5.56mm loads (The older [=M193=] for the former, and the current [=SS109=] for the latter.)[[/note]]* TheRival: Her resentment of FNC apparently stems from the fact that they share similar designs.* TokenHuman: Inverted. Both she and SPAS are the token ''guns'' to the school they attend.

A friend and classmate of AR 70/90, who meets up with the main cast at Enoshima. She is the personification of the Franchi SPAS-12 [[http://en.wikipedia.org/wiki/Franchi_SPAS-12]], a combat shotgun from Italy.----* GirlishPigtails* TokenHuman. Inverted.
